Part I. Computation of Community Completeness scores: The selected POIs (amenities) include park, convenience, restaurant, supermarket, library, wastewater plant. The selected time lengths for travel include 5, 10, and 15 minutes. The value of amenity preference are predetermined to be 0.7, 1.0, 0.5, 0.9, 0.8, 0.01 for park, convenience, restaurant, supermarket, library, wastewater plant, respectively. The corresponding amenity quantity are 2, 5, 30, 1, 1, 0. The decay function for amenity is assumed to be y = -log(0.5)/(amenity quantity). The analyses are as follows. 1. Map for all Points of Interest (POIs) in San Mateo County 2. Map (in block groups) for the selected 6 POIs for San Mateo County 3. Map for Redwood City block groups 4. Map of total, walking, cycling, and driving normalized completeness scores for selected POIs 5. Geographical comparison across sub-regions in Redwood City for total, walking, cycling, and driving normalized completeness scores 6. Comparison of completeness scores and percentages of scores over baseline (i.e. value >1 ) for including negative (unwanted) amenity and excluding essential (necessary) amenity in the communities of Redwood city (i.e. Wastewater plant is considered as a negative amenity for this case; whereas, the convenience stores is an essential amenity) 7. Geographical (sub-regions) comparison of completeness scores and percentages of scores over baseline for including negative amenity and excluding essential amenity in the communities of Redwood City. Part II. Equity analysis – population comparison by race using 2020 decennial census data 1. Map of Redwood City (blocks) within 5 min walking to POIs 2. Population comparison by race for San Mateo County vs. Redwood City within 5 min walking to POIs 3. Population comparison by race for Redwood City vs. Redwood City within 5 min walking to POIs Part III. The analyses (in blocks) of NHTS data were performed individually for geographical comparison of travel pattern among three regions: Bay area, San Mateo county and Redwood City. The analytical contents are as follows. 1. CBSAS map 2. Travel patterns for trip frequency, mileages, and duration(time length) by trip mode and trip purpose
